<strong><font size="4">功能特点：</font></strong>
<ul>
<li><strong><font size="4"></font></strong><font size="1">
<font size="3">坚固耐用</font>采用铝合金框架结构，坚固结实耐用。</font>
<li><font size="1">
小型<font face="Times new=" New? Roman?>/</font>轻量体积小，重量轻，方便携带。</font>
<li><font size="1">
电脑写频用户可通过电脑写频，设置各信道的频率及参数。</font>
<li><font size="1">
操作简单易用整机设计简洁，用户更易于使用。</font>
<li><font size="1">
信道存储采用频率合成技术，可存储16个半双工信道和1个扫描信道。</font>
<li><font size="1">
<font face="Times new=" New? Roman?>CTCSS</font>功能（选装配置）可加装38组标准CTCSS哑音频模块，方便用户组网或防止同频干扰。</font>
<li><font size="1">
省电功能
接收状态无信号输入时，自动进入省电守侯状态，以减少接收电路的耗</font><font size="1">电量，从而延长使用时间。</font>
<li><font size="1">
低电压警告
使用中，当电池的电压降低时，红色发光灯闪烁，并且发射时会发出鸣声提示，表示电池需要更换。</font>
<li><font size="1">
超时定时器
为了防止长时间占用信道并防止损坏功率管，通过编程可以对连续发射限时进行设置。</font>
<li><font size="1">
扫描功能
本权提供两种扫描模式：时间操作模式（TO） 、载波操作模式（CO）并可设置优先信道扫描，扫描信道可以被编程。</font>
<li><font size="1">
有线复制功能
只需通过一条写频线进行对讲机之间的复制。</font></li></ul><font size="1">
